For me, it's about knowing when to expect more of the promised functionality (that I've "groused" about previously :twisted: ) in the Silicon being exposed through the IDF. They claim a few things of the ESP32 that unless you have some enhanced IP licensing available to you, you're not going to be able to know if there's any other errata on the silicon or not- and you can't use the desired functionality. Some projects would call for BT Classic...and you can't DO that yet. Some projects call for their meshing solution...and you can't DO that yet...

:D

Hi there,

in order to use the latest esp-idf version from here which is the best way to "update" a running esp32 environment?
e.g.: if a I have a linux directory like /esp/esp-idf, do I only have to delete the existing esp-idf folder an just redo step 2 of your instruction from here?

best regards

Howdy,
Don't think of the ESP32 as desktop PC with an operating system onto which you can install upgrades and patches. Rather, think that the ESP32 runs ONLY one application at a time and that the application is a binary file which is "fixed in form" at compile time. When you run an ESP32 application, the ESP-IDF (the software development toolkit) is compiled INTO the application at that time. Once the application is deployed to the ESP32 there is no way to "patch" that running application. Instead what one would do is recompile the source of the application using a later version of the ESP-IDF and then re-flash the ESP32 device with the new copy of the application that is now at a later level.

I wonderif one should install det ESP32 software over again to get then new IDEv 2.0. I am working inside arduino IDE, and want to test BLE. If they have some new examples showing how to use the BLE inside arduino IDE, it would be great,but that might be to early?

Hello Neil,

does that mean I can't just upgrade my esp-idf folder in my linux system and compile with the new version?
(Sorry for my simplified thinking.)

Best regards

You can update an existing esp-idf folder like this:

Code: Select all

git fetch
git checkout v2.0-rc2
git submodule update --init

Hello Igrr, hello Neil,

that is indeed easy.

Thank you very much.

I seem to have an issue using rc2 with Arduino as a component (on an existing rc1 project):
